Get used to aperture priority.
Don't use manual, you'll use it 5% of the times.
Only use Manual if you use an external flash mounted on your camera.
Aperture priority -> ~ 85% of the times
Shutter priority -> ~ 10% of the times
Manual -> ~ 5% of the times
Read some beginner stuff, as soon as you learn what iso/aperture/shutter/exposition are, you're ready to go and start getting better on your own.
